so what is this a game like HS? or like studio to make animation? because i want to try it
Think about it as both in 1 Environment, more closely to Playstation Dreams but it's main target is Human Machine Interaction and Character(Avatar) Simulation you can do Game Logic as well.
You can create worlds inside of it but it is yet more limited than Dreams in those regards to very basic Primitive construction and you still mostly need a 3rd party DCC package for more complex construction based on Polygons only for now.
You can also think of it as another Realtime Desktop and VR Interface to Unity which it's based on same as HS, though it's a bit more limited in terms of Import/Export still as this is still entirely in the Hands of Unity and as such you still need the Unity Editor for more complex tasks and preparation, but only for the more complex content import (final stage).
Most use it for now to Create Interactive Animations for VR with Simulation Characteristics, lot of Experiments currently in all Kinds of Directions apart from just the Fapping Usecase
Being it different Interfaces on top of it or new Physic interaction ideas, a lot is going on think of it as the Next Generation of DAZ Studio in VR but with a far much wider possible usecase spectrum
For example you could already make it your Windows Login and Tifa Grants you access to your System doing the correct titty pinching and spank code or drawing the right way to your favorite spot, telling her a secret or ID yourself with showing her your dick if you like
